Incremental forming of multislope shaped components

In the last years, a number of studies on Incremental Sheet Forming have been focused on formability analysis and, in particular, on the development of models able to predict material response also in the design phase. Due to mechanics complexity, up to now process application is directly dependent on a preliminary experimental investigations based on the execution of trials and errors tests; a set of experiments, in fact, is necessary to determine the industrial feasibility. Of course this approach is very expensive and time consuming and, for this reason, new techniques to perform reliable guidelines for the designer are strongly requested. In the paper an effective statistical methodology has been applied with the aim to build a suitable base of knowledge minimising the number of experimental tests for identifying an optimal set of parameters which strongly impact on the process performance.
